Although there is little evidence so far that any of the human HDACs have specific gene-regulatory roles, it has been shown that HDAC4 and HDAC5, but not HDAC1 or HDAC3, can inhibit myogenesis by associating with MEF2 and repressing MYOD activity 41. Furthermore, studies ...

Cancer epigenetics
Cancer epigenetics is the study of epigenetic modifications to the genome of cancer cells that do not involve a change in the nucleotide sequence. Epigenetic alterations are as important as genetic mutations in a cell’s transformation to cancer, and their manipulation holds great promise for cancer prevention, detection, and therapy. In different types of cancer, a variety of epigenetic mechanisms can be perturbed, such as silencing of tumor suppressor genes and activation of oncogenes by altered CpG island methylation patterns, histone modifications, and dysregulation of DNA binding proteins. Several medications which have epigenetic impact are now used in several of these diseases.
